VVAPOR-BURNER OR PLUNIBERS TORCH.

SIFECIFICATION forming part of Letters Patent N0. 473,159, dated April 19, 1892.

Application filed December 9, 1891. Seria] No. 414,485. (No model.)

To all w/wm t may concern:

Be it known that I, HARRY ANDREW KER- SLAKE a, citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and usefulImprovements in Vapor-Burners or Plumbers Torches; and Ido hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable 1o others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements. in vapor-burners or plumbers torches adapted for use in connection with hydrocarbon fuel, preferably naphtha or gasoline, and particularly designed for use in various arts requiring the application of intense heat to a relatively small surface, as for the burning of paint, heating and fuszo ing small objects, and for soldering and various other purposes to which the blow-pipe is commonly applied.

The object of my invention is to provide a burner which requires no mechanical forced draft, which shall give out a steady and constant flame of high temperature, and which is simple in construction and operation, durable, and comparatively inexpensive; and it consists` of the construction and combination 3o of parts disclosed and claimed in the following specification, of Which the accompanying drawings form a part, wherein similar numerals of reference designate like or equivalent parts Wherever found throughout the several views, and in which- Figure 1 is a side elevation; Fig.`2, a central section; Fig. 3,a detailshowing the wick; Fig. 4, a plan View With chimney and hood removed.

4o Referring to the drawings, reference-number 1 designates the reservoir or oil-pot, of any desired material, which should be capable of resisting considerable internal pressure, say fifty pounds to the square inch. The

top ofthe reservoir is provided with an annular depression or cavity 2, and from the center of this concavity rises a nozzle or extension 3, either formed integrally with or secured to the reservoir and forming a wick- 5o holding socket, the top or cover of Which is provided with a nipple or gas-j et discharge 4,

having an aperture of exceedingly small caliber, which communicates directly with the interior ot' the reservoir.

Vithin the reservoir is the wick 5, preferably round in crosssection, and the upper end thereof is preferab@ 'lclosed in a cap 6, of wire gauze or cloth, iirmly secured thereto, the spaces between the Wires forming passages for oil or vapor, and the body of the 6o Wick is preferably wound with wire 7 to keep the wick in shape and to control to an extent the capillary action thereof, and thus limit the amount of oil or other substance which will Vpass through the wick to the point of vaporization, as hereinafter described. It will be seen that this wire Wrapping serves simply as a compress or stricture upon the Wick by which its capillary action is retarded or regulated, and it is evident that devices 7o other thana wire Wrapping might be employed with similar results, and it will also be seen that the Wire cap 6 aids in producing the result specified. By this construction the too free supply of naphtha or other substance at the point of vaporization is prevented, as is also to a great extent the- Overflow thereof when the device is not inV use, so common in this class of burners. The upperend of the Wick, with its wire cap 6, is adapted to lit 8o tightly into the extension 3, so as to fill the latter in such manner that the fuel can reach the opening in the nipple only by means ofr capillary action lthrough the Wick. l

4Fit-ting tightly over the extension 3 is the 85 tube 8, within which is What is known as the mixing-chamber of an ordinary Bunsen burner. The tube 8 is provided with airingress openings 9, and the air as it enters through these openings 9 mingles with the vapor as it escapes from the nozzle 4, and the product is burned as it escapes from the outer end of the tube S. The tube S is formed of any desired material capable of resisting high degrees of heat and is preferably curved, as shown.

The reservoir is provided with a screwcapped filling-orifice 10, and preferably with a pair of handles 1l, and a hood 0r cover 12, attached to the reservoir by means of a bayoroo net-joint consisting of locking-studs 14 and angular slots 15 and provided with air-openings 13, incloses the tube S and serves as a shield and draft-guard in windy weather.

The operation of my invention is as follows: The reservoir is tirst whollyor partially filled with naphtha and the filling-aperture closed. rlhe annular cavity 2 is then lled with naphtha and ignited and the hood or cover 12 placed in position. The heat generated by the combustion of this free naphtha or other fuel heats the nozzle and upper part of the reservoir and volatilizes the naphtha within that is nearest the nipple, through which the hydrocarbon gas so generated gradually escapes to the mixing-chamber. This gas ultimately ignites through the openings 9 from the flame outside the tube 8, and, combining with the indratt of air from without, issues from the end of the tube as a blue and intensely hot ame. The naphtha originally placed in the cavity 2 and ignited is intended only to produce heat for the initial volatilization of the naplygli in the reservoir, the parts being all formed o heat-conducting material, and when burned out need not be renewed, since the heat evolved by the burning jet is ample to generate gas for said iet and for the internal pressure required to force the gas through the nipple.

The depressed top ol the reservoir itself furnishes the simplest and best means for holding the naphtha or other material to be first burned for the generation ot vapor; but it will of course be understood that a vessel might be employed for this purpose either secured to the tube S or entirely detachable, and many other changes in the construction and combination of parts may be made without departing from the scope of my invention, andI do not limit myself to the exact construction and arrangement of parts shown; but,

Having fully described said invention, its construction and operation, I claim and desire to secure by Letters Patent the following:

l. The combination, with a reservoir provided with a cover having an upward extension adapted to hold a wick and provided with a vapor-discharge opening, of a wick provided with a compress and held in said extension, substantiallv as shown and described.

2. The combination, with a reservoir provided with acover having an upward extension adapted to hold a wick and provided with a vapordiscl1arge opening, of a wick provided with a compress and held in said extension and means for heating the extension and generating vapor, substantially as shown and described.

The combination, with a reservoir the top of which is provided with a wick-holding socket having a vapor-discharge opening in its top, ot' a wick held and secured in said socket and means for heating the said socket and generating vapor, substantially as shown' and described. 1

4. The combination, with a reservoir the top of which is provided witha wick-holding socket having a vapor-discharge opening and an oil or naphtha holder adjacent thereto, of a wick heldin and suspended from said socket, substantially as shown and described.

5. The combination, with a reservoir the top of which is provided with a wick-holding socket having a vapordischarge openin g, of a wick held and secured in said socket and a tube surrounding the same and connected therewith, provided with air-ingress openings, and means for heating the parts and generating vapor, substantially as shown and described.

6. The combination, with a reservoir the top of which is provided with a wick-holding socket having a vapor-discharge opening and a cavity adjacent to said socket, of a wick provided with a compress and held in said socket and a tube provided with ai r-in gress openings surrounding the vapor-discharge opening, substantially as shown and described. l 7. The combination, with a reservoir the top of which is provided with awick-holding socket having a vapor-discharge opening, oi a wick provided with a compress held in said socket, that end of the wick within the socket being inclosed within a cap having passages foroil orvapor, substantially as shown and described.

8. The combination, with a reservoir the top of which is provided with a wick-holding socket having a vapor-discharge opening, of a wick provided with a compress and held in said socket, substantially as shown and described.

9. The combination, with the reservoir of a vapor-burner or plumbers torch, of a wick provided with a compress, whereby the capillary action of the wick is limited.

In testimony whereof Iallix my signatu re in presence of two witnesses.
